Serum antibody titers to bovine respiratory syncytial virus were determined for 559 cattle. Serum samples were obtained through the Minnesota State-Federal Brucellosis Laboratory and were collected over a 1-year period. Results of this study revealed an antibody prevalence of 65.5% to bovine respira...

Quercetin was able to reduce the cytotoxic effect of T-2 mycotoxin on cultured murine thymocytes. When given to mice immediately before challenge with T-2 mycotoxins, quercetin significantly reduced mortality.

An indirect haemagglutination test (IHA) and ELISA technique were developed to detect antibodies against Eimeria tenella. The ELISA technique was relatively easy to perform, more sensitive than the IHA test, and needed only a fraction of the antigen required for IHA. The highest titers using ELISA w...

Pooled seminal plasma obtained from six bulls was tested for its immunosuppressive activities in vitro on blastogenesis of bovine lymphocytes. Lymphocyte stimulation assay and mixed lymphocyte reaction were used as test procedures. Concanavalin A and phytohemagglutinin were utilized in the lymphocyt...

This study describes the isolation and partial characterization of a low molecular weight (approximately 14 kDa), cadmium-binding protein from rainbow trout (Onchorynchus mykiss) liver. Rainbow trout were injected intraperitoneally with 3.5 mg/kg cadmium chloride (total body dose) twice weekly for 3...

An anionic detergent, sodiumdodecylbenzenesulphonate, had an adjuvant effect upon aerosol allergic sensitization with subtilopeptidase A, a proteolytic enzyme of Bacillus subtilis. Both local and systemic antibody responses were accelerated and prolonged by use of the detergent. This adjuvant effect...

The effect of vitamin E injections on immune responses of calves was investigated. Treatments were: 0, 900, 1800 and 2700 IU of D-alpha-tocopherol given by injection starting at birth and then a 3 wk interval until the age of 12 wk. Plasma vitamin E levels were significantly higher for supplemented ...
